Description

[Detailed Description of the Invention] The present invention relates to an improvement in a tensioning structure for extending an automotive ceiling sheet inside a ceiling panel.

As a conventional tension structure of this kind, for example, the first
There are some types as shown in Figure 2.

In the conventional tension structure, as shown in the figure, the support member 1
is composed of a single round rod, which is inserted into each of the plurality of suspension bags 3 formed on the back surface of the ceiling sheet 2, and both ends of each support member 1 are perforated in the ceiling rail 4. By linearly engaging the plurality of locking holes 5,
The structure was such that the ceiling sheet 2 was stretched inside the ceiling panel 6.

However, in this conventional tension structure, since both ends of each support member 1 are simply engaged with the locking holes 5 of the ceiling rail 4, as shown by the imaginary lines in FIG. During assembly work, each of the supporting members 1 tends to flip downwards using the locking hole 5 as a fulcrum, resulting in a major problem in that work efficiency is significantly reduced.

The present invention was devised in view of the problems with the conventional tension structure, and includes a support member that is divided at arbitrary locations, and a connecting member that connects each divided end of the divided support member. , a connecting member that connects the supporting members connected by the connecting member, the connecting member is composed of one member and another member, and the dividing member is attached at one end of the one member and the other member. The split end of the support member forms a fitting part into which the split end is rotatably fitted, and a fitting part is formed at the other end of both members to rotatably connect one member to another; A mounting portion for fitting the end of the connecting member is formed on the side surface of the member and the other member, and an intermittent portion is further formed at an appropriate position of the hanging bag of the ceiling sheet, and an intermittent portion is formed in the intermittent portion. By adopting the configuration in which the connecting member is positioned, the above-mentioned conventional problems are attempted to be solved.

Hereinafter, the present invention will be described in detail based on an illustrative embodiment.
The support member 10 may be constructed of a round bar as before, or it may be constructed of a C-shaped pipe, a hollow pipe, etc. in order to reduce weight. By connecting the parts with a connecting member 11, which will be described later, a single-length structure is adopted. In addition, in the drawing, a C-shaped pipe is used for the connecting member 10.

The connecting member 11 is a molded product made of synthetic resin, and specifically, as shown in FIGS. One member 11a has a fitting part 12 to which the ends are fitted, one end has a convex fitting part 14 which fits into the recessed fitting part 13, and the other end has a fitting part 12 with the split end. The fitting portion 12 of each member 11a, 11b and the supporting member 1
By rotatably fitting the respective divided ends of 0, and at the same time rotatably fitting the concave fitting part 13 and the convex fitting part 14, one member 11a and the other member 11b are connected. The structure is such that the divided support members 10 can be connected into a single piece.

Furthermore, each member 11a and 11b of the connecting member 11
In order to connect the adjacent support members 10, mounting portions 15 for fitting the ends of the connecting members 16 are provided on the side surfaces of each of the adjacent support members 10.
A structure in which adjacent support members 10 can be sequentially connected by making the attachment parts 15 of each connection member intervening at the dividing point alternately face each other, and by attaching a rod-shaped connection member 16 between each attachment part 15. It is also connected.

Moreover, a suspension bag body 17 provided on the ceiling sheet 2
In this case, intermittent portions 18 are formed at locations where each connecting member 11 is located when the supporting member 10 is inserted.

Therefore, when the ceiling sheet 2 is stretched inside the ceiling panel using the tension structure having such a configuration,
First, the support members 10 in a divided state are inserted into the bags 17 of the corresponding ceiling sheets 2, and one member 11a and the other member 11b constituting the connecting member 11 are inserted into the divided ends of each support member 10. At the same time, the one member 11a and the other member 11b are connected via the concave fitting part 13 and the convex fitting part 14, and the divided support member 10 is connected to the normal fitting part 12. Make it one piece.

Next, one member 11a constituting the connecting member 11
and the mounting portion 15 of the other member 11b, and the mounting portions 15 of the one member 11a and the other member 11b of the adjacent connecting member 11 are arranged so that they alternately face each other.
After rotating and correcting the uneven fitting of 1a and 11b,
A linking member 16 is attached between each opposing mounting portion 15 to sequentially link adjacent support members 10 to each other as shown in FIG.

In this state, if both ends of each support member 10 are engaged with the corresponding locking hole 5 of the ceiling rail 4, each support member 10 will not be reversed downward.
The ceiling sheet 2 can be reliably stretched inside the ceiling panel 6.

As described above, the present invention utilizes a connecting member that connects the divided parts of a divided support member to form an attachment part of the connecting member that connects supporting members adjacent to the connecting member, and connects the attachment part with the connecting member. Since it is characterized by successively connecting adjacent support members through members, it is completely possible for the support members to flip downward using the locking holes of the ceiling rail as fulcrums during assembly work as in the past. This makes it possible to significantly improve work efficiency.

Further, the existence of a connecting member that connects adjacent supporting members can improve the rigidity of the mutual relationship between the supporting members, and at the same time can greatly contribute to improving the rigidity of the entire ceiling.

Furthermore, since the connecting member can be partially removed in the present invention, it goes without saying that it can be easily applied to ceiling structures that form daylight windows in automobile ceilings, which have become popular in recent years.

Moreover, since the connecting member itself is composed of one member and the other two members, and the one member and the other member are fitted in a concave-convex manner, the one member and the other member can be disassembled to form a split support member. Since it is possible to fold the ceiling sheet through which the ceiling sheet is inserted, handling of the ceiling sheet is also extremely convenient.

Furthermore, by connecting split support members with a connection member, the length of the support members to be connected in a single shape can be freely determined by changing the length of the connection member, so it is possible to freely determine the length of the support members that are connected in a single shape. The present invention has the advantage that supporting members can be shared among various types of automobiles.
